Italy's vibrant capital lives in the present, but no other city on earth evokes its past so powerfully. For over 2,500 years, emperors, popes, artists, and common citizens have left their mark here. Archaeological remains from ancient Rome, art-stuffed churches, and the treasures of Vatican City vie for your attention, but Rome is also a wonderful place to practice the Italian-perfected il dolce far niente, the sweet art of idleness. Your most memorable experiences may include sitting at a caffè in the Campo de' Fiori or strolling in a beguiling piazza.

Days at sea are the perfect opportunity to relax, unwind and catch up with what you’ve been meaning to do. So whether that is going to the gym, visiting the spa, whale watching, catching up on your reading or simply topping up your tan, these blue sea days are the perfect balance to busy days spent exploring shore side.

The medieval cliff-hanging town of Taormina is overrun with tourists, yet its natural beauty is still hard to dispute. The view of the sea and Mt. Etna from its jagged cactus-covered cliffs is as close to perfection as a panorama can get—especially on clear days, when the snowcapped volcano's white puffs of smoke rise against the blue sky. Writers have extolled Taormina's beauty almost since it was founded in the 6th century BC by Greeks from nearby Naxos; Goethe and D. H. Lawrence were among its well-known enthusiasts. The town's boutique-lined main streets get old pretty quickly, but the many hiking paths that wind through the beautiful hills surrounding Taormina promise a timeless alternative. A trip up to stunning Castelmola (whether on foot or by car) should also be on your itinerary.

Malta's capital, the minicity of Valletta, has ornate palaces and museums protected by massive fortifications of honey-color limestone. Houses along the narrow streets have overhanging wooden balconies for people-watching from indoors. Generations ago they gave housebound women a window on the world of the street. The main entrance to town is through the City Gate (where all bus routes end), which leads onto Triq Repubblika (Republic Street), the spine of the grid-pattern city and the main shopping street. Triq Mercante (Merchant Street) parallels Repubblika to the east and is also good for strolling. From these two streets, cross streets descend toward the water; some are stepped. Valletta's compactness makes it ideal to explore on foot. City Gate and the upper part of Valletta are experiencing vast redevelopment that includes a new Parliament Building and open-air performance venue. The complex, completed mid-2013, has numerous pedestrian detours in place along with building noise and dust. Before setting out along Republic Street, stop at the tourist information office on Merchant Street for maps and brochures.

Trapani, the most important town on Sicily’s west coast, lies below the headland of Mount Erice and offers stunning views of the Egadi Islands on a clear day. Trapani’s Old District occupies a scimitarshaped promontory between the open sea on the north and the salt marshes to the south. The ancient industry of extracting salt from the marshes has recently been revived, and it is documented in the Museo delle Saline. In addition to the salt marshes,Trapani’s other interesting environs include the beautiful little hill town of Erice, the promontory of Capo San Vito stretching north beyond the splendid headland of Monte Cofano, the lovely island of Motya and the town of Marsala. Trips farther afield will take you to the magnificent site of Segesta or the Egadi Islands, reached by boat or hydrofoil from Trapani Port.

Tunisia's capital lies at the western end of the shallow Lake Tunis, which opens to the sea at La Goulette. This is the first of a string of beach suburbs that stretches away to the north; it is here that the city's port is located. This coastal area includes the ruins of ancient Carthage and the picturesque suburb of Sidi Bou Said, places that attract more visitors than Tunis itself. As far as capital cities go, Tunis has an easy-going, unhurried air about it. It is a very liberal city by Islamic standards and certainly leading the way in Western trends for the rest of the country. In Tunisia, the struggle for independence didn't take the violent course that it did in Algeria. Ruler Ahmed Bey, who governed from 1837 to 1855, encouraged Westernization and brought in military and other advisors to this end. In 1861, during the reign of Mohammed Sadiq, a constitution - the first in the Arab world - was proclaimed. Until the time of the French protectorate, the medina was very much the center of things. Then, under the French influence, the ville nouvelle (new city) emerged with its major banks, department stores, and administrative services. The main focus of ville nouvelle is the wide, tree-lined Avenue Habib Bourguiba. At its western end, this major thoroughfare becomes the Avenue de France, terminating in the Place de la Victoire and the entrance to the medina.

Known in Sardinia as Casteddu, the island's capital has steep streets and impressive Italianate architecture, from modern to medieval. This city of nearly 160,000 people is characterized by a busy commercial center and waterfront with broad avenues and arched arcades, as well as by the typically narrow streets of the old hilltop citadel (called, simply, “Castello”). The Museo Archeologico makes a good starting point to a visit. The imposing Bastione di Saint Remy and Mercato di San Benedetto (one of the best fish markets in Italy) are both musts.

Days at sea are the perfect opportunity to relax, unwind and catch up with what you’ve been meaning to do. So whether that is going to the gym, visiting the spa, whale watching, catching up on your reading or simply topping up your tan, these blue sea days are the perfect balance to busy days spent exploring shore side.

If you look north of the cathedral (La Seu, or the seat of the bishopric, to Mallorcans) on a map of the city of Palma, you can see around the Plaça Santa Eulàlia a jumble of tiny streets that made up the earliest settlement. Farther out, a ring of wide boulevards traces the fortifications built by the Moors to defend the larger city that emerged by the 12th century. The zigzags mark the bastions that jutted out at regular intervals. By the end of the 19th century, most of the walls had been demolished; the only place where you can still see the massive defenses is at Ses Voltes, along the seafront west of the cathedral.

A torrent (streambed) used to run through the middle of the old city, dry for most of the year but often a raging flood in the rainy season. In the 17th century it was diverted to the east, along the moat that ran outside the city walls. Two of Palma's main arteries, La Rambla and the Passeig d'es Born, now follow the stream's natural course. The traditional evening paseo (promenade) takes place on the Born.

If you come to Palma by car, park in the garage beneath the Parc de la Mar (the ramp is just off the highway from the airport, as you reach the cathedral) and stroll along the park. Beside it run the huge bastions guarding the Almudaina Palace; the cathedral, golden and massive, rises beyond. Where you exit the garage, there's a ceramic mural by the late Catalan artist and Mallorca resident Joan Miró, facing the cathedral across the pool that runs the length of the park.

If you begin early enough, a walk along the ramparts at Ses Voltes from the mirador beside the cathedral is spectacular. The first rays of the sun turn the upper pinnacles of La Seu bright gold and then begin to work their way down the sandstone walls. From the Parc de la Mar, follow Avinguda Antoni Maura past the steps to the palace. Just below the Plaça de la Reina, where the Passeig d'es Born begins, turn left on Carrer de la Boteria into the Plaça de la Llotja (if the Llotja itself is open, don't miss a chance to visit—it's the Mediterranean's finest Gothic-style civic building). From there stroll through the Plaça Drassana to the Museu d'Es Baluard, at the end of Carrer Sant Pere. Retrace your steps to Avinguda Antoni Maura. Walk up the Passeig d'es Born to Plaça Joan Carles I, then right on Avenida de La Unió.

One of the best ways to arrive in Catalonia is by sea, especially via the Costa Brava. This coastline, also known as the Rugged or Wild Coast, stretches from Blanes to the French border. Its name aptly refers to the steep cliff of ancient twisted rocks, which runs its entire length and is bounded inland by the Catalan mountain ranges. The intensity of the coast’s colour, the ruggedness of the rocks and the scent of the plants all combine to add to its attraction. The history of this region is long and varied. Traces can be found of the advanced culture of the Iberians, Greeks, Romans, Visigoths and Arabs. With Wilfred I and the independence of Catalan countries, the Catalan dynasty was born. Later, in 1479, Catalonia became a part of unified Spain following the marriage of Isabel, Queen of Castile, and Fernando, King of Aragon. The port of Palamos, some 36 miles northeast of Barcelona, has been in existence for nearly 700 years thanks to its location on one of the deepest natural bays in the western Mediterranean. The town itself is the southernmost of a series of resorts popular with sun worshippers. For the most part, Palamos has managed to retain some of the charm of a fishing village. The port also serves as a gateway to such inland locations as Girona, the capital of the province. Art lovers may want to visit Figueras, famous for its bizarre Teatre-Museu Dali, the foremost of a series of sites associated with the eccentric surrealist artist, Salvador Dali. If you choose to stay in Palamos, you can enjoy the pleasant atmosphere of the town or spend some time at a nearby beach. The town has a long seagoing tradition and busy harbour. The fish auction, prompted by the arrival of the fishing boats, is a spectacle worth seeing. The Fishing Museum illustrates the history and the life of the families who live off the sea.

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.
